The Wikipedia page seems to show that it's just a placebo/scam? The helmet has the equivalent magnetic effect of a fridge magnet or hair dryer, and researchers in Sweden replicating the research in a double-blind study found no effect at all. Looking at the pictures on the official website https://www.god-helmet.com/wp/god-helmet/index.htm , it's just magnets on a snowmobile helmet this guy bought.
Thhe "God helmet" was likely a placebo device. From the very same Wikipedia article you linked:
> Other groups have subsequently found that individual differences such as strong belief in the paranormal and magical ideation predict some alterations in consciousness and reported "exceptional experiences" when Persinger et al's experimental set-up and procedure are reproduced, but with a sham "God helmet" that is completely inert or a helmet that is turned off.
Symplectic integrators are the approach I used for some old galaxy simulations. Page 5 on the attached paper was my main reference, eq 22

I believe this is used in several academic codes for long term N-body calculations.
Thank you for the feedback! This is a great idea and definitely fits into the vision.
Do you know if the FPGA and/or hardware communities use any type of formalism for design or documentation of state machines? One example of what I mean is is Harel statecharts - essentially a formalized type of nested state diagram.
Hello? We have 17(!) federally funded national labs, full of scientists doing the work this article waxes nostalgic about. Through the Laboratory Directed Research and Development (LDRD) program they afford employee scientists the ability to pursue breakthrough research. However, they are facing major reductions in funding now due to the recent CR and the upcoming congressional budget!
I was a post doc and applied to an LDRD. It's not a free for all, they, the institution, already knows what topics want to fund and you write your proposal to cater to that. Very similar to tacking "AI" to your pitch these days.
It's an illusion that no-strings-attached funding exists. The government has an agenda and you're free to research anything you want, as long as it is one of the pre-determined topics. It's a very political process.
The headline is a lie. It doesn’t even try to support it in the article. They were asked if they can support the agenda that is literally their job to support.
I recently made the switch to linux full time as well. Even small things, like my computer taking three seconds from clicking Shutdown to turning off, is such a relief compared to Win11.
attrs looks interesting, can it be used in workflows for processing GBs of data? I don't see any Cython compatibility or other Python to compiled code options. I typically just get by with numpy recarrays, but I'm old fashioned and looking for something more modern.
Attrs would not replace your record array. IIRC you can supply slots so it might be useful for converting raw data into your numpy types, but I suspect you'd find the overhead in function calls problematic
If you want easier than recarray and almost as fast I think you're in pandas-ville
